1.
Purpose:
AOAC SMPRs describe the minimum recommended performance characteristics to be
7
used during the evaluation of a method. The evaluation may be an on‐site verification, a single‐
8
laboratory validation, or a multi‐site collaborative study. SMPRs are written and adopted by AOAC
9
Stakeholder Panels composed of representatives from the industry, regulatory organizations,
10
contract laboratories, test kit manufacturers, and academic institutions. AOAC SMPRs are used by
11
AOAC Expert Review Panels in their evaluation of validation study data for method being considered
12
for
Performance Tested Methods
or AOAC
Official Methods of Analysis
, and can be used as
13
acceptance criteria for verification at user laboratories.

Applicability
:
16
The method will be able to identify, and quantify each individual cannabinoids
(as listed in Table 1a
17
and Table 1b) in dried plant materials.

Analytical Technique
:
20
Any analytical technique(s) that measures the analytes of interest and meets the following method
21
performance requirements is/are acceptable.

25
Limit of Quantitation (LOQ)
26
The minimum concentration or mass of analyte in a given matrix that can be reported as a
27
quantitative result.

Quantitative method
30
Method of analysis which response is the amount of the analyte measured either directly
31
(enumeration in a mass or a volume), or indirectly (color, absorbance, impedance, etc.) in a certain
32
amount of sample.
33
34
Repeatability
35
Variation arising when all efforts are made to keep conditions constant by using the same
36
instrument and operator and repeating during a short time period. Expressed as the repeatability
37
standard deviation (SD
r
); or % repeatability relative standard deviation (%RSD
r
).
